title Ambiguity in Art and Science
source International Conference on Generative Art
summary Ambiguity can be defined as the coexistence and/or coalescence of two incompatible aspects in the same reality. Ambiguity manifests itself * in pathologic processes occurring in matter, e.g. at the critical state of the solid ¬ ® liquid phase transformation. * during the process of measurement of quantum structures: a process formally very similar to the process of perception. * Systematically, in our mind, during the process of perception - especially during visual perception of paintings or acoustic perception of music.Therefore ambiguity is an intrinsic feature of the process of perception and an intriguing step in the way toward the formation of thought. Ambiguity is continuosly experienced in our mind: every act of perception culminates into the critical state of a dynamic instability of the interiorized image, where the incoherent heap of sensory stimuli merges into coherent visual or auditive thinking. In turn, since perception is essential for life, we should look at ambiguity not so much as to a fastidious travel companion, but rather as to a fixed course toward perception itself, scientific thought and aesthetic emotion: ambiguity is a permanent cultural value.

summary The rapid development of the potentialities of multimedia imposes a reflection about its use in teaching architecture. Multimedia is multifaceted and each facet deserves a particular attention inasmuch as it can change the traditional approach to learning. A direct experience of an architectural work can be simulated with a impact far stronger than an experience trough photographs, drawings and books can do. But, as every positive fact can have in certain cases also some negative consequences. the intensity of the participation to an experience structured by someone else can leave less space to a personal approach to the object of the presentation. The same problem is posed if we consider the structure of an hypertext. The essence of the hypertext lies in the net of relationships between very different kinds of documents that it is able to manage in order to express the complexity of its theme. But who has to create the net, the teacher choosing the relationship that he thinks important or the learner to build a personal image of the hypertext matter. It is an old question about the two faces of teaching: transmitting knowledge or giving the learner the instruments to build by oneself his store of knowledge. Easy and trivial answer that both approaches can be useful. The accomplishment of a multimedial sequence of average complexity requires at present a lot of time. Hence, to be convenient, it is to be used many times, then by many students. The effectiveness of the tool partly depends on the rapidity with which it can be constructed. Speeding it up would allow to use this kind of tools with the same easiness than mare traditional means of representation. Besides those general considerations a check is to do on the peculiarities, if any, of the use of multimedia in the different disciplines of the formative curriculum of an architect. This is theme of our thirteenth conference. The programme has been articulated into sessions, dealing separately with history teaching, design teaching and research. Of course the sessions dealing with design are more numerous than the other, since design is the axis of teaching architecture. The presented paper cover a large arc of arguments, dealing with many facets of the proposed themes with plenty of examples and documentation on practical experiences. constituting a corpus of great usefulness for any operator in the field of architectural teaching.

title Image Recognition: from Syntax to Semantics
source Challenges of the Future [15th eCAADe Conference Proceedings / ISBN 0-9523687-3-0] Vienna (Austria) 17-20 September 1997
summary n a previous paper the authors presented an analyser of simple architectural images. It works at syntactical level inasmuch as it is able to detect the elementary components of the images and to perform on them some analyses regarding their reciprocal position and their combinations.

Here we present a second step of development of the analyser: the implementation of some semantic capabilities. The most elementary level of semantics is the simple recognition of each object present in the architectural image. Which, in turn means attributing to each object the name of the class of similar objects to which the single object is supposed to pertain. While at the syntactical level the pertinence to a class implies the identity of an object to the class prototype, at the semantic level this is not compulsory. Pertaining to the same class, that is having the same architectural meaning, can be objects having approximately the same shape. Consequently in order to detect the pertinence of an object to a class, that is giving it an architectural meaning, two things are necessary: a date base containing the class prototypes to which the recognized objects are to be assigned and a tool able to "measure" the difference of two shapes.

summary Collaborative Design is a topic of particular current interest. Existing software allows a multiplicity of designers to work on the same project. What the software really allows is accessing to a part of the information of the project and changing it. Sometimes there is a hierarchical distribution of the power of change: some participants can be permitted to operate only on some limited layers of the object representation. In this case the changes they propose are to be accepted by a general manager of the design process. What is lacking in this kind of software is the explicit management on the reciprocal constraints posed by different participants. In this paper, an elementary Collaborative Design System is presented whose main concern is just the management of constraints. Each participant designs the part of the project of his/her concern instantiating objects comprised of geometric description, alphanumeric variables and constraints on both. Constraints can be of two types: absolute or defined by a range of allowed values of the constrained variable. A participant intervening later can accept the constraint, choosing a value in the permitted range, or decide to violate it. In this case the proposed violation is signalled to whom posed it.

summary This research focus on the application of Theory of Games and asymmetry information to the AEC sector underling the impact of these theories to the supply chain and in particular on the evolution of the client role in a Building Information Modeling process. The mentioned theories used to be applied to macroeconomic fields, but allowed the researchers to understand the evolution of the sector and the internal behavior of the team. This analysis of team behaviors permits to grasp how the contractual frame could hold up the natural trend of the market to collaborate, which leads the sector to improve itself. The Theory of Games could be adopted as a hermeneutic tool for understanding actions and agreements to which the various parties achieve. The research provided a global analysis on the evolution of the client role in a cyclical process. Further development of the research will be the application of the theory to a real case study to catch the real team behavior in a collaborative environment.

summary Despite his controversial political background, the leading architect of the Italian Rationalist Movement, Giuseppe Terragni, has attracted the attention of a large group of architectural scholars. He has often been acknowledged as an enigmatic figure whose architecture oscillated between classicism and modernism. This work offers formal generative analyses of the Mambretti Tomb and the Danteum, which are seen as the ‘quintessence’ of Terragni’s architecture. It provides a formal generation of these two projects in the form of parametric shape grammar. In doing so, this paper aims at unfolding the generative process of both projects in order to gain a deeper understanding into the ways that formal construction of Terragni’s architecture expresses meaning.

summary Creativity is an important factor for innovators. According to Eguchi and Pinheiro (2008) the basis of design is innovation because of the use creative methodology. It’s important to remember that the word “project” comes from the Latin “proyectus”, meaning “a forward throwing action”. According to Ramos (2006), “educating for creativity is essential.” Beetlestone (2000), De Bono (1993), Munari (1997) and Pawlak (2000) argue that as we’re children we’re curious to find answers to everything, but that traditional schooling brakes the creativity. This research is a methodological test which aims to identify the reasons for student’s selection of specific creative tools used in university projects.

summary The research presented is about digital revolution in architecture, which has contributed to the birth of new figurative trends. The work was conducted through the definition of a framework to identify and classify architectural design elements that should be attributed to the methods and techniques of design computing, then applied to sixty prominent recent architectures which are acknowledged products of digital means. The early results suggest that a new era is coming, where the conceptual starting point of designers is often born in the digital space, taking advantage of the augmented representation skills to control and manipulate form. We will also do an overview of these new architectural trends, discussing both causes and cultural roots and identifying eventual criticisms and further developments.

summary Besides design theory and practice, curricula of architectural students should include some experiences referring to professional situations. Among these experiences, Collaborative Design is nowadays somewhat frequent. It is normally practised by large professional studios, using expansive software which is beyond what they can afford on average. Much academic research on the topic has also been carried out often resulting in the proposition of new and too complex description models of the building object. We think that students should instead get acquainted with such a design process: an experience has been planned and carried out in our Department for the purpose of practising the possible paradigm in a more ordinary context. Its purpose was threefold. First, making the students grasp the method’s potentialities and learn the right approach. Second, testing the practical suitability of the most widely used software. Third, comparing their relative efficiency. The software we used was: Architectural Desktop, AutoCad Revit, ArchiCad for Teamwork. We focused special attention on how representing and managing restraints, since they are the main source of conflicts. This was the hardest topic to manage. The results were partly positive inasmuch as the experience showed that it could be possible to adopt the Collaborative Design paradigm which is also used in the AEC field. The drawbacks emerged from the analysis of non-dedicated software are: a relative slow process for the lack of certain specific tools; a subsequent necessity of integrating them with different communication software; the difficulty of managing hard and soft restraints. However, in the final analysis, the experience can be considered as positive.

summary A paper, a description of a software application is given, which allows to generate tridimensional models of buildings, directly inside a geo referential context, following a parametric approach, in which the volume of the building is put in direct relation with forces/law bonds emerging from the urban context. The user is, therefore, able to interactively operate within a project process, in which, by changing the parameters values and by verifying in real time, the results of the changes, he/she is able to evaluate all possible infinite scenarios. The system, thought for Trento’s (Italy) urban context, may also be applied on other cities.

summary In this paper we present a new parametric approach based on environmental constraints, in order to generate digital models of architectural shape, directly within a three dimensional geo-referenced environment. Those constraints may be regarded as force fields with a specific spatial dimension. The system allows user, through implementation of specific generative procedures, to manage interactive architectural design processes. The designer is able to explore all possible infinite scenarios and the various possible design alternatives, by changing the parameters values and verifying in real time the results of the changes.

summary The final configuration of the architectural shape is deeply conditioned by all constraints that the environmental context imposes. These, duly codified, can therefore generative elements that can be managed by the designer. Following a parametric approach, the architectural envelope is directly related to the constraints emerging from the urban context. In this paper we present the development and implementation of an application, which allows to generating three-dimensional models of buildings, directly within a three-dimensional geo-referenced environment. The application offers the user many innovative suggestions, associating the modeling ability, typical of the CAD systems, to the opportunity offered by the geo-referenced systems, to evaluate in real time the impact of the buildings directly on its environment, within which it can be generated and manipulated. The designer is able to explore several alternative solutions, according to formal requirements and style preferences. Three experiments are presented for different urban scenarios.

summary Today’s explosive developments in digital technology have also affected architecture and urban landscape. The new possibilities opened up by digital simulation have led to an increasingly strategic approach to planning, an approach based on generating scenarios, which thus represents a radical departure from traditional planning. But, up to now, what is the prevalent trend in architecture? Can we talk yet in term of language? Or have the extreme freedom in design destroyed the style? In this paper we present an analysis of the contemporary architecture, strongly influenced by digital technologies, through an objective analysis of several case-studies and we show the first result of this in progress research.

source CAADRIA 2008 [Proceedings of the 13th International Conference on Computer Aided Architectural Design Research in Asia] Chiang Mai (Thailand) 9-12 April 2008, pp. 300-208
summary Two innovations have more deeply changed the building process: the operational continuity of the design and construction phases and the software allowing not only the representation but also the autonomous creation of complex shapes never before thought, just because they could not be represented. This last innovation introduce to a “Performative Architecture” that addresses to emerge a new kind of architecture. Building performances (structural, environmental, energetic) are guiding design principles, adopting new building performance-based priorities for the design of cities, buildings and landscape. This emerging architecture places broadly defined performance above form making; It utilises digital technologies of quantitative and qualitative performance-based simulation to offer a comprehensive approach to the design of the build environment. Some aspects of “Performative Architecture” theories are critically examined and we report two experiments made using these procedures. The results try to give a contribution to detect some misunderstandings in relation to recent building projects shown.

source SIGraDi 2002 - [Proceedings of the 6th Iberoamerican Congress of Digital Graphics] Caracas (Venezuela) 27-29 november 2002, pp. 159-162
summary This paper re-establishes the theoretical framework for participatory design evolved in the late sixties and early seventies as part of the movement towards a more explicit design methodology and attempts an explanation of why the concept failed to gain commitment from the architectural and urban design professionals. The issue of user participation in the processes of building and urban design is enjoying renewed attention following its relative neglect over the last 20 years due, in large measure, to significant advances in emerging information technologies, particularly multimedia, virtual reality and internettechnologies. This paper then gives an account of two significant and relevant developments in the evolution of the application of informationtechnologies with which the authors have been engaged. These are:a responsive and interactive interface to wholly immersive and realistic virtual reality representations of proposed buildings and urban neighbourhoods. an intuitive and platform-independent VR modelling environment allowing collaborative evolution of the scheme from withinthe virtual world. The efficacy of these IT developments is tested in the context of a design exercise in which three designers, from distributedlocations and using different computer platforms, collaboratively design an Information Centre from within the virtual world.

title Real Teaching and Learning through Virtual Reality
source International Journal of Architectural Computing vol. 1 - no. 1
summary This paper addresses an articulated vision of Virtual Reality, which lends itself to design collaboration in teaching, learning and communication of architectural design ideas among students, design professionals and client bodies during the early stages of the design process. Virtual Reality (VR) has already acquired a new degree of complexity through development of network-based virtual communities and the use of avatars. A key intrinsic quality of VR technology is to support collaborative design experience. The design tools developed for this experiment are capable of creating 3D objects in a shared VR environment, thus allowing the design and its evolution to be shared.The choice of programming language (JavaTM) reflects the desire to achieve scalability and hardware independence, which in turn allows for the creation of a VR environment that can co-exist between high-end supercomputers and standard PCs. The prototype design environment was tested using PC workstations and an SGI system running in a Reality Centre.

summary In the last decades, urban design has been influenced by its relationship with landscape. This has led to a new approach formalised and called Landscape Urbanism. Defining specific reading and analysis instruments together with proper design methods, capable of a transdisciplinary dialogue with geography, plant and biological world's languages, landscape urbanism can undoubtedly obtain more performing purposes than the ones achieved by traditional urban planning. Moreover, new digital tools are appearing, providing urbanism with new instruments for an advanced and interactive way to design cities in close relationship with landscape. The process starts with the acquisition of large quantity of data, like georeferenced maps in conjunction with relevant information about the territory, such as traffic and atmospheric pollution data, important buildings and monuments or significant landscape elements (rivers, mountains, etc.). All this information is combined onto multiple layers in order to be used by different design algorithms, connected by multi-dimensional arrays, whose reciprocal relations are dynamically controlled by architects and engineers. We will present here the case study of an ecological and regenerative infrastructure for the city of Bergamo designed on the basis of these principles, using a convenient combination of parametric tools.
